Abstract: In accordance with the Multip le Allele Hypothesis, the genetic male sterile lines 00S107 in non-heading Chinese cabbage 〔Brassica campestris L. ssp.chinensis (L. ) Makino〕was used as a source of male sterility and the fertile lines‘Qinggeng Milk Cabbage’as goal parent. The gene of male sterility was
transferred to ‘Qinggeng Milk Cabbage’ by crossing, selfing, sibling and test crossing. After three years transferring, a new AB line TypeⅠ, a new male sterile line, and its corresponding temporarymaintainer line of‘Qinggeng Milk Cabbage’was obtained.

Key words: Brassica campestris L. ssp. chinensis (L. ) Makino, Genetic male sterile line, Transfer
